bottom. wall 12 In the coal pit is located As shown herein, the aperture 21 in the leaf a hopper 13 open at the front and adapted 1 20 is elongated in a direction at right angles to fit within the coal pit. Said hopper has side walls 123, 13*, adapted for sliding move- 2 ment with reference to the side walls of the coal pit, and a downwardly and forwardly inclined bottom wall 13* adapted to rest upon the bottom wallet said coal pit. The bottom wall of the hopper is connected at its forward edge by means of hinges 20 as will presently be described, so that the hopper a whole is capable of forward swinging ing movement is imparted to the hopper when desired, by means of a reciprocatory plunger 14 operating in a cylinder 15 and adapted to be actuated by compressed steam or other fluid controlled by means located in the cab of the engine conveniently to the hand of the fireman. The controllin r and operating means may be such as des ribed in the patents heretofore referred to, and said means forms no part of the present invention, a further description of it will be unnecessary.

The bottom wall 13 of the hopper consists of a metal plate or sheet 16 and of spaced parallel longitudinally. extending angle bars 17, whichare rigidly secured to said plate 16 by rivets or otherwise. The side walls of the hopper consist of plates or sheets of metal rigidly secured to the outermost angle bars 17. The bottom wall of the hopper does not rest directly on the bottom zeal 12" of the'coal pit but on transversely extending plates 18, 19 and 19, secured to the top surface of said bottom wall; the plate 18 being located beneath the forward end of'the hop er, the plate 19 near its rear end and the p ate 19 at a point spaced between the first two named plates. As shown, the plate 18 does not extend continuously across the bottom wall of the coal pit, but

comprises a series of shorter plates 18,

arranged end to end with their adjacent ends spaced apart to provide room for the hinges 20.

The hinges 20 areof such construction that while they will hold the hopper against forward or backward longitudinal movement in the bottom wall of the coal pit, they will at the same time allow a limited flexibility ofmovement between the leaf of the hinge connected at the bottom wall of the coal pit and the leaf connected to the bottom 7 As shown herein, said hinges each comprise a leaf 20 rigidly secured at the forward end of the bottom wall 13 of the bopper; a leaf 20? rigidly secured to the bottom wall 12 of the coal pit intermediate the adjacent ends of the bars 18; and a pintle 20 which en- I of the hopper. in a directionsubstan-- tially at right angles to said bottom wall.

to the plane of the hinge when open, as clearly appears in Figs. 5 and 6. 'l he apex tures 2'2 in the leaf 20 are of a diameter to receive the pintle snugly, which prefer ably rigidly secured therein by means of set screws 20. (See Fig. 10). The front end 13 of the hopper bot tom wall terminates in a line intermediate the lateral edges of the plate 18 and extends preferably to aline w'ertically below the pintles of the hinges movement about said forward edge. Swmgi except at the hinges where notches 125 are ward end of its bottom wall bearing on the plate 18, acts as a fulcrum about which the hopper, as a whole, is swung. (See Fig. 4.) The sole function of the hinges during this movement is to prevent the hopper from sliding longitudinally forward on the bottom wall of the coal pit, and the slot in the .leaf connected to the hopper, permits'said' leaf to move with reference to the pintle of the hinge, so that the'pintle will not resist this movement. -The weight of the hopper and of the coal contained in it instead of coming on the pintles of the hinges is exerted by the forward end of the bottom wall of the hopper on the bar 18. This prevents strain on the hinge pintles and thusobviates the breaking of the connection at the hinges. In addition, shoulda luinp or lumps of coal, when the hopper is raised, vfall between the bottom wall of the hopper and the bottom'wall of the coal pit and come to lodge adjacent the hinges, even if said lump or lumps were not crushed by the weight of the hopper in its descent, their resistance to the crushing strain acting to lift the front end of the hopper would resultin no damage to or breaking of the hinge connection, since the play allowed between the leaves of the hinge would read ily permit the one member of the hinge at tached to the bottom wall of the hopper to rise with reference to the other member attached to the bottom wall of the coal pit without placing any strain on the hinge pintles.

In order to prevent coal from entering between the side walls of the hopper and the side walls of the coal nit along the forward edges of said side walls of 'the hopper, the following construction is provided. The plates comprising said sidewalls 13 of the hopper are curved outwardly at their forward edge toward the side wall 12 of. the

coal pit at 13. Covering each side wall -of the coal pit throughout a space slightlylarger than the segment through which theforward edge 13* of the hop er side wall is adapted to'swing, is locate a filler consisting of angle bars 24, 25 arranged to inclose thesegment of a-circle with the center substantially coincident with the axes of the hinges and between which are placed'filler blocks 23 which are covered by a segmental plate 26. A third angle bar 24 is arranged parallel to and spaced from the angle bar 24 to form a slot or way in which is located a strip preferably of wood, 27, ada ted. to engage with .the side wall of the iiopper. Said strip is held in engagement with said side wall by means of'springs 26* which act between the bottom of said strip and the side wall of the coal pit so as to hold said stri yieldingly in engagement with the side wail of the hopper. This construction revents any coal from passing between the side wall of the hopper and the side wall of the coal pit.

I claim as my invention- 1. In an engine tender of the kind described, in combination with a coal pit located therein, a swinging inclined member adapted to agitate the coal in the pit to feed it toward its forward end, said swinging member resting at its forward end on the bottom wall of the coal pit and being adapted to be swung on the bottom wall of said pit about said forward end as an axis. and means for hinging said swinging member to the bottom wall of said coal pit, said means providing a limited movement between the forward end of said swinging member and the bottom wall of the coal pit in a direction at right angles to the latter.

2. In an engine tender of the kind described, in combination with a coal pit located therein, a swinging hopper having side walls and an inclined bottom wall located within said coal pit, the forward end of the bottom wall of said swinging hopper hinging said resting on the bottom wall of the coal pit, said hopper being adapted to beswung about said forward end of its bottom wall as'an axis on the bottom wall of said coal pit, hinge memhere for hinging said swinging hop er to the bottom wall of said coal pit, said in s being constructed to provide movement etween the forward end of said swinging hopper and the bottom wall of the coal pit in a direction at right angles to the latter.

3. In an engine tender of the kind described. in combination with a coal pit located therein. a swinging inclined member adapted to agitate the coal in the pit to feed it toward its forward end, a transverse late secured to the bottom wall of said coa it, said swinging member resting at its orward end on said transverse plate and being adapted to be swung on said plate about its forward end as an axis, and means for swinging member to the bottom wall of said coal pit, said means pro viding a limited movement between the forward end of said swinging member and the bottom wall of the coal pit in a direction at right angles to the latter.

4. In an engine tender of the kind de scribed. having a coal pit with side and bottom walls, a hopper having bottom and side walls, means providing a between the bottom wall of said hop er and the bottom wall of said coal pit, am. yield ing filler members interposed between the side walls of said hopper and the side walls of said coal pit.

In testimony. that I. claim the foregoing as my invention resence of two witnesses. this 24th day of hlovember A. D. 1911.
